一种基于自动测试系统软件适配器的虚拟通道通用管理方法A general management method of virtual channel based on automatic test system software adapter

技术领域technical field

本发明涉及测试技术领域，特别涉及一种基于自动测试系统软件适配器的虚拟通道通用管理方法。The invention relates to the technical field of testing, in particular to a general management method of a virtual channel based on an automatic testing system software adapter.

背景技术Background technique

在自动测试系统（Automatic Test System，以下简称ATS）中，由软件构建被测件（Device Under Test，以下简称DUT）端口与测量仪器之间信号经过的路径，称为虚拟通道，对应于DUT端口与测量仪器之间的物理通道连接。由于DUT端口与测量仪器的连接之间往往需要引入开关网络、电缆、转接器、放大器或衰减器等辅助性器件及设备，然而这些器件或设备会引入插入损耗、失配等测量误差，直接影响测试结果的准确性。In the automatic test system (Automatic Test System, hereinafter referred to as ATS), the path through which the signal passes between the device under test (Device Under Test, hereinafter referred to as DUT) port and the measuring instrument is constructed by software, which is called a virtual channel, corresponding to the DUT port A physical channel connection to a measuring instrument. Since the connection between the DUT port and the measuring instrument often needs to introduce auxiliary devices and equipment such as switch network, cable, adapter, amplifier or attenuator, but these devices or equipment will introduce measurement errors such as insertion loss and mismatch, directly affect the accuracy of test results.

为了提高测试准确度，需要专门的软件获取通道的插入损耗，供ATS软件在测试DUT时进行数据补偿。此类软件称为自动测试系统软件适配器（简称ATS软件适配器），ATS软件适配器是通过测试得到通道的插入损耗数据，此数据用于DUT测试时误差修正，提高测试准确性。In order to improve the test accuracy, special software is needed to obtain the insertion loss of the channel, which can be used for data compensation by ATS software when testing DUT. This type of software is called Automatic Test System Software Adapter (ATS Software Adapter for short). The ATS Software Adapter obtains the insertion loss data of the channel through testing. This data is used for error correction during DUT testing to improve test accuracy.

图1为现有ATS软件适配器的技术方案框图，以下给予详细的介绍：Fig. 1 is the block diagram of the technical solution of the existing ATS software adapter, and the detailed introduction is given below:

（1）ATS软件适配器根据ATS中开关网络设备端口组合固定的虚拟通道序列，该序列不可修改，虚拟通道数目固定；(1) The ATS software adapter combines a fixed virtual channel sequence according to the ports of the switching network equipment in the ATS. The sequence cannot be modified, and the number of virtual channels is fixed;

（2）ATS软件适配器为所有虚拟通道配置统一的测试激励信号频率列表和功率。测试通道插入损耗的补偿修正涉及多个频率点，在进行数据补偿时，通过线性插值算法获得给定频率对应的插入损耗数据。因为频率点与测试的插入损耗一一对应，如果改变频率列表，所有已测试的虚拟通道的插入损耗数据将清空，需要重新测试。如果测试的不同DUT，测试频率范围可能不同，而又需要覆盖所有DUT的测试频率范围，那么频率列表的范围也就变得很大，为适应数据补偿差值算法的精度要求，就需要相应增加测试点数，这样就提高了测试时间；因此，为了提高测试效率，每个通道都应可以单独配置激励信号，以便于ATS能同时对DUT进行测试；(2) The ATS software adapter configures a unified test excitation signal frequency list and power for all virtual channels. The compensation correction of the insertion loss of the test channel involves multiple frequency points. When performing data compensation, the insertion loss data corresponding to a given frequency is obtained through a linear interpolation algorithm. Because the frequency point corresponds to the insertion loss of the test, if the frequency list is changed, the insertion loss data of all tested virtual channels will be cleared and a new test is required. If different DUTs are tested, the test frequency range may be different, and the test frequency range of all DUTs needs to be covered, then the range of the frequency list becomes very large. In order to meet the accuracy requirements of the data compensation difference algorithm, it needs to be increased accordingly. The number of test points will increase the test time; therefore, in order to improve the test efficiency, each channel should be able to configure the excitation signal separately, so that the ATS can test the DUT at the same time;

（3）ATS软件适配器以固定的激励仪器和测试仪器对所有虚拟通道进行测试，获取功率插损数据。对所有通道进行测试的激励与测试仪器设备固定不可更改，如果ATS中有多于1台的信号源或功率计，用户可能需要选择其中任一台作为激励仪器或测试仪器，就不能满足测试需求。(3) The ATS software adapter tests all virtual channels with fixed excitation instruments and test instruments to obtain power insertion loss data. The stimulus and test equipment for testing all channels are fixed and cannot be changed. If there are more than one signal source or power meter in the ATS, the user may need to choose any one of them as the stimulus or test instrument, which cannot meet the test requirements. .

现有的ATS软件适配器都是专用的、且不灵活，其具有以下缺点：Existing ATS software adapters are all dedicated and inflexible, and have the following disadvantages:

（1）虚拟通道序列固定，如果需增加通道而更换开关网络设备无法满足ATS升级或扩展需求。(1) The sequence of virtual channels is fixed. If it is necessary to add channels and replace switch network equipment, it cannot meet the needs of ATS upgrade or expansion.

（2）所有虚拟通道的测试激励信号的频率列表相同。如果修改频率列表，所有已测试的虚拟通道的插入损耗数据将清空，需要重新测试。另外，由于各个通道连接的DUT种类可能不同，因此它们的测试频率范围也不尽相同，如果为了覆盖所有DUT的测试范围，频率列表的范围也就尽量的大，为适应数据补偿差值算法的精度要求，就需要相应增加测试点数。(2) The frequency list of the test excitation signal is the same for all virtual channels. If the frequency list is modified, the insertion loss data of all tested virtual channels will be cleared and a new test is required. In addition, since the types of DUTs connected to each channel may be different, their test frequency ranges are also different. To cover the test range of all DUTs, the range of the frequency list should be as large as possible. In order to adapt to the data compensation difference algorithm Accuracy requirements, it is necessary to increase the number of test points.

（3）所有虚拟通道的测试激励信号功率相同。由于DUT的测试需求，需要在不同的通道中分别连接放大器、衰减器，这样通道间的插入损耗差别就很大，如果所有通道使用同一个固定激励信号功率，对于有些通道，经过通道的插入损耗，输入到测试仪器的功率有可能超过仪器的测量范围，无法完成测试。(3) The test excitation signal power of all virtual channels is the same. Due to the test requirements of the DUT, amplifiers and attenuators need to be connected to different channels, so that the insertion loss between channels is very different. If all channels use the same fixed excitation signal power, for some channels, the insertion loss through the channel , the power input to the test instrument may exceed the measurement range of the instrument, and the test cannot be completed.

（4）所有虚拟通道的测量仪器固定。如果用户需要更换测量仪器进行通道插入损耗的测试，就无法满足需求。(4) The measuring instruments of all virtual channels are fixed. If the user needs to replace the measuring instrument to test the insertion loss of the channel, it cannot meet the demand.
